Module E1 - Slide 61


Many people are confused about the installation of APS with pretimed signals or signals on recall, where pushing a button is not needed. The APS can function without a need for the button to be pressed. They can and should be set so the audible walk sound plays whenever the visual walk is displayed. Without that, many sighted people may not understand the APS functioning when the locator tone is sounding and there is never a walk.

It doesn't hurt anything if someone presses a button when it's not needed either.
